Ils sont extr\u00eamement utiles. Mais ils sont aussi tr\u00e8s chers. Dans ce tutoriel, je vais vous montrer comment fabriquer un oscilloscope simple et bon march\u00e9 avec un Raspberry Pi Pico.<\/p>\n\n\n\n<p>Cet oscilloscope - que j'appelle \"Picoscilloscope\" - s'articule autour d'un Pico et de l'application Scoppy sur un appareil Android. Vous pouvez l'utiliser pour d\u00e9tecter et analyser des signaux de basse tension.<\/p>\n\n\n\n<p>Je vais donc vous montrer ici comment construire un oscilloscope super bon march\u00e9 en utilisant un Raspberry Pi Pico W et une disquette en 5 \u00e9tapes faciles.<\/p>\n\n\n\n<p>Je vais le faire avec un smartphone, mais vous pouvez aussi le faire avec une tablette. Tant que vous avez Android 6.0 ou une version plus r\u00e9cente, vous devriez \u00eatre pr\u00eat.<\/p>\n\n\n\n<p><strong>AVERTISSEMENT<\/strong>: L'\u00e9lectricit\u00e9 est dangereuse. Soyez prudent et veillez \u00e0 ne pas utiliser l'oscilloscope d'une mani\u00e8re qui pourrait vous blesser ou blesser d'autres personnes. Cet oscilloscope Pico ne fonctionne qu'avec des signaux de basse tension et de basse fr\u00e9quence et ne doit \u00eatre utilis\u00e9 que dans ces cas.<\/p>\n\n\n\n<p>Cette configuration d'oscilloscope est con\u00e7ue pour d\u00e9tecter des tensions inf\u00e9rieures \u00e0 3,3V. Si vous souhaitez aller plus loin, vous pouvez en savoir plus. <a href=\"https:\/\/github.com\/fhdm-dev\/scoppy\">ici<\/a>.
